Details:
This Monday, January 16, the sun is peppered with numerous sunspots contained in 9 active regions.
In this image I want to represent the three wavelengths in which an amateur astrophotographer can capture the sun.
In violet we can see the sun in the K line of calcium (CaK), in the ultraviolet zone, in yellow we can see it in white light (540nm) and in orange we see the wavelength of hydrogen alpha (Ha) located in the 656.3 nanometers.
Which "flavor" of this solar cake do you like the most?
To take this picture I used a 90mm (Ha) Coronado Solarmax II telescope. A Sky Watcher Esprit 120 telescope with a Lunt B1800 calcium module (CaK) and the same telescope with a Herschel Baader prism with a 540nm (WL) filter.
For the 3 photographs I used a ZWO 183MM camera
